Hello,
Thank you for providing further details and for following up.
In that case, I would suggest you to do the following:
1. Assign each item in your Drinks category a tag, lat’s say tagA, except from the one you don’t want to have any limits on.
2. Then go to the Products section and disable the Per product option and enable the Per product tag option.
3. Then go to Products > Tags > TagA > Edit and set the Min quantity to 3.
P.S. Your settings in the General section should be the same.
Please give it a try. Please let me know if it doesn’t help.
Kind regards,
Moshtafizur
